The first Wednesday of each month, the MHARS 9 PM net holds a “Tech Night” to discuss ham related technical questions. This month we discussed power supplies and the pros and cons of linear or analog power supplies, as well as switching power supplies and the issues that can arise when using them. See our recent post on switching power supplies. Other topics covered were batteries and rapid voltage drops of a Li-On battery, and a host of other topics. Stop by with your questions and somebody will certainly have an answer, an opinion, or know where to find the answer. Be sure to join us on June 1st for the next Tech Night!
